Simple Agreement for Future Equity (SAFE)
A Simple Agreement for Future Equity (SAFE) is a contractual instrument used in early-stage startup financing that grants an investor the right to receive equity in a future priced round rather than immediate shares or debt repayment. SAFEs carry no maturity date, accrue no interest, and do not create a debtor-creditor relationship, distinguishing them from convertible notes. The two most common economic terms are a valuation cap -- the maximum company valuation at which the SAFE converts -- and a discount rate, which lets the investor purchase shares at a percentage below the price paid by new investors in the triggering round.
Problem & Application
A founder raises $250,000 on a SAFE with a $3 million valuation cap and a 20 percent discount. Two years later, Series A investors price the round at a $6 million pre-money valuation at $1.00 per share. The SAFE investor converts using the cap-derived price of $0.50 per share (3M divided by 6M, applied to $1.00), receiving 500,000 shares rather than the 250,000 shares a new investor buys with the same $250,000. The discount clause would have yielded $0.80 per share, so the cap applies as the more favorable term. Founders must model post-conversion cap tables carefully -- stacking multiple SAFEs with aggressive caps can result in unexpected dilution when a priced round closes.
In Short
SAFEs provide an efficient way for startups to raise early-stage funding, but founders must carefully structure agreements to maintain control and equity balance.
